You need to focus on the aspect ratio and panel layout. Webtoons usually have a vertical scroll format, so make sure your panels flow smoothly in that direction.
It depends on the terms and conditions you agreed to when you uploaded or submitted your comic to Webtoon. If you didn't carefully read and understand those, it's hard to say for sure.
The key to creating your webtoon comic is having a clear vision. Work on the script, practice your drawing skills, and experiment with different styles. And don't forget to get feedback from others to improve.
There was a case where a cellmate was a pathological liar. He would spread false rumors about his cellmate to the other inmates, which led to the innocent cellmate being ostracized and even facing threats. It was a really difficult situation for the one being lied about as he had to constantly defend himself.
There was this gay prison cellmate story. One cellmate was in for a minor offense. The other had been there for a while. The new cellmate was scared at first. But the older one showed him the ropes. They bonded over their shared identity. They would pass the time by talking about their favorite books and movies. And they made a pact to always be there for each other, which was really important in that harsh prison environment.
Well, it takes a lot of planning and creativity. First, you need a great story idea. Then, start sketching out your characters and their designs. And don't forget to practice your drawing skills regularly!
